Possible 9/11 victim remains have been discovered among the mountains of debris left over after the World Trade Center crumbled, the New York Daily News reports.

Eleven and a half years after the Sept. 11 terrorist attacks on the World Trade Center, investigators are still combing through the debris carted off to Staten Island after the two towers collapsed. And on Monday, the New York City medical examiner announced that two possible human remains were found among the rubble.

The search for human remains among the mountains of World Trade Center debris continued oearlier this week after a three-year hiatus. The roughly 60 truckloads of material hauled off during the construction of the new World Trade Center has been sitting, untouched and all but forgotten, in the Fresh Kills landfill on Staten Island since 2010. Investigators will spend the next 10 weeks sifting through the debris, looking for any fragments of bone or tissue which could be used to identify a victim.

"We have been monitoring the World Trade Center site over time and monitoring the construction and if they see any material that could possibly contain human remains, we collect that material," Ellen Borakove, a spokeswoman for the medical examiner's office, told The Daily Mail.

Of the 2,750 people killed at the World Trade Center on Sept. 11, 2001, 1,116 have yet to be identified. Almost 10,000 human remains recovered from the ruins remain in storage at an undisclosed location, but are too degraded for DNA testing.

The Deputy Mayor Cas Holloway said in a memo Friday that investigators will continue to test remains for DNA until every possible identification can be made.

The Daily Mail reports that effort to identify Sept. 11 victims has always been a contentious issue, especially after the city's chief medical examiner, Charles Hirsch, told families back in April 2005 that identification efforts would be suspended. According to Hirsch, his office had exhausted the possibilities of identifying human remains using DNA technology.
